CARL SEVERIN JOHANSON, OF MONTCLAIR, NEW JERSEY.

EXTENSION-WINDOW GUIDE. If

Specification of Letters Patent.

Application filed January 25, 1917. Serial N 0. 144,496.

To all whom it may concern:

Be it known that I, CARL SiwnnIN JorIAN- son, a citizen of the UnitedStates, and a resident of 92 WValnut street, Montclair, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Extension-Window Guides, of which the following is aspecification.

This invention relates to extensible windows and especially to thatclass wherein a sash is secured to the outermost of a series oftelescoping frames and guided by linearly extensible horizontal rods.

An illustration of a window wherein this invention may be used is foundin my Patent No. 1,209,164, patented Dec. 19, 1916.

One advantage of this invention is to provide guides for an extensiblewindow which will be smooth in operation.

Another advantage is to provide window guides which are perfectlysynchronous in action.

Another advantage is to provide an extensible window which is operatedby pulling either of a pair of chains or cords.

Another advantage is to provide an extensible window which may beprojected or retracted by pulling one of a pair of chains or cords, orby turning a crank mounted upon a shaft rotatable by means of saidchains or cords.

Further advantages and possibilities will become apparent as thespecification proceeds.

Throughout the drawings, the same numerals or letters denote the sameparts.

Figure 1 is an outer view of an apparatus embodying this invention. Fig.2 is a vertical sectional view of Fig. 1, and is cut centrally throughsome parts. Fig. 3 is a diagrammatic top view of a modification. Fig. 4is a similar View of Fig. 1. Fig. 5 is an interior View of Fig. 1, withpart of 22 torn away.

My invention comprises primarily a hollow prismatic frame 22 bearing lip27 and flange 81, by which latter it is secured to wall frame 30. Aboveframe 22 and beneath the same are a corresponding pair of large slotsinto which are fitted the flush plates 3 and 6. Secured to these are thesquare sleeves 9 and 9 and feed shafts 8 and 23. In these sleeves 9, 9,are slidably fitted the square rods 5 and 5, which carry sash 1'?provided with glass 16 and screen frame 18 by means of blocks 13 and 13and collars 14 secured to the vertical shafts on square collars 15.

Extending upward from screen frame 18 through slot 2 in plate 3 andthrough slot 9 in sleeve 9 is the vertical feed bar 11. Similarly, lowervertical feed bar 11 extends down from screen frame 18 through slot 6 inplate 6 and through slot 9 into sleeve 9. The feed bar 11 is secured tothe frame 18 by means of bolt 10 and to guide bar 5 by extension and nut5 in sleeve 9. The upper feed bar 11 is similarly secured to thecorresponding parts.

The screw feed shafts 8 and 23 are mounted in hearings in the plates 6and 3 and are provided with pulleys 7 and 4, respectively, by which theymay be rotated. These pulleys are connected by a chain or cord denoted21 and 29, providing for synchronous rotation of both shafts 8 and 23.If a handle 12 is used to rotate shaft 8 clockwise, the sash 17 andframe 18 will be drawn inward by means of feed bars 11 and 11 climbingthe threads of shafts 8 and 23, and passing inward in slots 9, 6, 2 and9. If the handle 12 is rotated anticlockwise, the frame 18 and sash 17will be projected outward from the building, the action beingcorrespondingly opposite to that of the previous case.

It is not imperative to use handle 12, however, as the above operationsmay be performed by merely pulling either cord 21 or 29, in which casethe handle may be dispensed with.

The rollers 1 in stop 1, 19 and 25 in sleeves 9 and 9 and 20 and 26 inguide bars 5 and 5 are all intended to reduce the friction and increasesmoothness of operation generally.

In Fig. 5 the hinged frame 24 is shown opened to expose flange 81, wallfacing 30, and plates 6 and 3. Frame 24 fits snugly about the edges 28of frame 22 when closed, as in Fig. 2. The plates 8' and 8' are set inframe 24 to aid in supporting shaft 8 when rotating the latter by handle12.

It will be noted that if chains or cords 21, 29 were spread apart topresent positions immediately within edges 28, as indicated by dottedlines ac and 661, the principle involved is not altered in any manner.In this case it would be necessary to introduce pulleys as indicated atpoints a, b, 0, cl, the purpose being to remove 21 and 29 from a.

central position to accessible side positions where they would notobstruct or mar the View.

If screen frame 18 should be detached from sash 17, the latter would befree to swing into any position if guides 5, 5, be extended distanceoutward, as illustrated in Fig. 4.

In Fig. 3 the guide 5 is shown as being on one side rather than in thecenter, the result being that sash 17 would be able to swing more to oneside if the frame 18 is detached, than were the guide 5 centrallylocated.

In Fig. 5 edge 28 has been torn away at 70 to expose slot 6 in plate 6and to especially illustrate the position of said plate in relation tobase surface s in which 6 is fitted flush. The rear parts of screenframe 18 and feed bar 11 which should be evident in 70 have been omittedto clearly show slot 6' in plate 6.

Having thus fully described my invention, what I claim as new and desireto obtain by Letters Patent is:

1. A window including an extensible frame bearing a sash, guide rodsadapted to slide horizontally secured at their outer ends to said sash,and at their inner ends to bars extending to the inner extremity of saidextensible frame, means for supporting said guide rods, and means forreciprocating said rods.

2'. A window including an extensible frame bearing on its outer edges asash as an integral part thereof, slidable horizontal guide rods securedat their outer extremities to said sash, and at their inner extremitiesto bars secured to the inner edges of said extensible frame, a feed nuton each of said bars and horizontal screw feed shafts engageable by saidfeed nuts, said shafts being adapted for manual rotation and horizontalsupports for said guide rods.

3. A window including an extensible frame and horizontally slidableguide rods attached at their outer ends directly to said frame, and attheir inner ends to bars pro vided with feed nuts secured to the inneredges of said frame, screw feedv shafts engageable by said feed nuts,and longitudinally slotted bearing plates supporting and concealing saidfeed shafts, said feed nuts communicating through said plates from saidshafts to said frame.

4:. A window including an extensible frame and horizontally disposedguide bars attached at both extremities to said frame to provide supporttherefor in horizontal movement, plates bearing screw feed shaftsdisposed parallel to said bars, and feed nuts secured to the latter toprovide longitudinal movement thereof upon rotating said screw feedshafts, extensions upon said plates to provide supports for said guidebars there being pulleys on said shafts and a cord connecting saidpulleys to provide synchronous rotation of said shafts.

5. A window including a horizontally slidable frame riding on horizontalguide bars secured thereto at both extremities, screw feed shaftsarranged parallel to said bars and supported by longitudinal platesprovided at the extremities with bearings therefor, sleeves with rollerssecured to said plates provided and adapted to receive said guide bars,and feed nuts engaging said feed shafts secured to the inner extremitiesof said guide bars, there being slots in said sleeves and plates toprovide passage for the connections between said inner extremities ofthe guide bars and aforesaid slidable frame.

Signed at 132 Nassau street, in the borough of Manhattan in the countyof New York, city and State of New York, this 23rd day of January, A. D.1917.
